Question

an object of hundred kg is accelerated uniformly from a velocity of 5 metre per second to 8 metre per second in 6 seconds.
calculate the initial and final momentum of the object, also find the magnitude of the force exerted on the object .......

Answer 1

m = 100 kg
u =5m/s
v = 8 m/s
initial p = ?
final p =?
F = ?

P = u × m
P = 500 kgm/s

P = m ×v
P = 800 kgm/s

a = v-u /t
a = 5-8 / 6
a = 3/6
a= 1/2 m/s2


F = m × a
F = × 1/2
F = 50 N
